RESPIRATORY APPARATUS.

Specification of Letters Patent. Patented Feb. 7, 1922 Application filed March 5,1921. Serial No. 449,846.

particularly to an apparatus for bringing about a thorough and effective circulation of blood and nerve fluid of the body and brain, my object being the provision of a-simple effective apparatus of this nature which may be eiliciently utilized in home or self treatment and whose beneficial results maybe obtained with little if any trouble and loss of time.

The use of my improved apparatus for the purposes above mentioned is based on the theory that disease and ill'health arise from stagnation of the blood and nerve fluids of the body and that this stagnation may be averted and its disastrous influences checked by complete circulation of fresh clean air through the lungs and brain cavity with the removal of all or practically all im are air.

y the use of my improved apparatus impure air may first be drawn out of the body and clean fresh air forced into the body and a constant circulation of air then enforced for a sufficient time to insure exercise and full expansion of the lungs and bronchial tubes as well as free circulation through the perforated bone of the cranium. In this way the blood may be forced to go through the blood passages of the body with greater force and effect and the brain may be caused to circulate the nerve fluid with greater force and effect through the spine and among the various nerves of the body.

In the accompanying drawings which illustrate my present invention and form a part of this specification,

Figure 1 is a perspective view illustrating the practical application of my invention in use, I

Figure 2 is a vertical sectional view I through the casing,

Figure 3 is a top plan view with the handle of the pump rods removed,

Figure 4 is a horizonttl section taken substantially on line 4-4 of Figure 2, I Figure 5 is an enlarged vertical section through the upper portion of filter tubes,

Figure (3 is an enlarged vertical section thrpugh the base of one of the pump barrels, 2LI1( Figures 7 and 8 are sectional side views illustrating slightly modified forms of the one of the apparatus.

teferring now to these figures my invention proposes an apparatus including air pumping means preferably in the nature of a pair of pump barrels 10 and 11 mounted vertically within an upright hollow casing 12, a section 13 of the wall of which is detachably connected thereto as by means of screws and the like to form a removable door. The top 14 of the casing 12 is also removably attached to the upper portion or edge of its wall, and the base 15 thereof is preferably providedwith diametrically outstanding extensions 16 forming foot rests.

Upstanding through the top 14 of the casing are the pumprods 17 and 18 operating plungersin the pump barrels 10 and 11, the former of which controls action in an exhausting line and the latter of which controls action in an air pumping line. Both of these lines are for their major portion in the nature of elongated flexible tubes externally of the casing 12, the exhaust line being indicated at 19 and the pumping or pressure supply line at20, bothdetachably connected'at 21. to pipes of which one ipe is indicated at 22 and the other at 23. hese pipes extend from air filter tubes 24 and 25 within the casing 12, held inupright positime against the inner surface ofthe wall of the casing as by means of clamps 26 and arranged to contain an air cleansing fluid as for instance clean pure water through which air is drawn in the case of the filter tube 24 through a suction pipe 27 leading from the base 28 of the pump barrel 10. In the case of the filter tube 25 air is forced into and through the water from an'air feed v tending outwardly through the casing top 14 for connection at 36 with a flexible tube 37 having at its outer end a mouth piece 38 as seen in Figure 1 for a purpose which will bepresently described.

The pump barrel 11 takes in air through an air intake pipe 39 which leads upwardly through the casing top 14 and connects at 40 with a flexible air intake hose or tube 41 for extension out of a window and the like in case the apparatus is used in a room. The pump barrel 10 discharges through a discharge pipe 42 which leads from the casingtop 14 and may be connected at 4?) to a flexible tube or hose 44 the latter of which like the intake hose 41 may beextended out of a window in case the apparatus is used within a room.

Each of the filter tubes 24 and 25 may have an upright pipe 45 extending upwardly through thetop 14 of the casing and pro vided with a pressure gauge 46, one of these gauges indicating pressure below atmospheric and the other indicating pressure above atmospheric. The upper ends of the two pump rods 17 and 18 may be connected by a single handle 47 which'upon being grasped and moved up and down sets both pumps in operation so that through the connections above stated, air will. be drawn toward the apparatus through the flexible ex= haust tube 19 which in practice becomes an exhaling tube, and air will be forced in the opposite direction through the pump or pressure tube 20 which in practice becomes an inhaling tube. V

In the ordinary use of my improved apparatus for the-purposes first above stated the exhaling or exhaust tube 19 is first con nected at its outer end to one of the nostrils exhaust of the air from the body. When the tube 19 is released the patient then draws a deep natural breath, removes the exhaust tube 19 and places the pressure tube 20 in one nostril, closing the other nostril and the mouth. The handle 47 is again raised and lowered so as to pump clean purified air into thebody until the patient is forced to release the tube At'this time all or practically all foul air-has been eliminated from the body while during the initial or exhausting operation st'agnated'blood has-been drawn into tlielungs and stagnated nerveifluid into the brain. During the second 'or pressure supply operation the blood and nerve fluids have been forced out of the-lungs and brain.

through the blood channels of the body and thenerves.

19 and 20 separately, that is first exhausting air from the body and then pumping air into the body, and thereafter for an appreciable time say from five to ten minutes the two air lines 19 and 20 are utihzedin conyunction, withthe line 19 in one nostril and the line 20 in the other nostril as shown in Figure 1. During this latter and cor inuous operation the patient inhales from tye air pressure line 20 as the pump actuating handle 47 descendsand exhales through the air line 19 as the pump handle 47 ascends. During.

this operation the mouth is of coursekept vclosed and it becomes quite obvious the patient may in any and all of these operations freely manipulate the pump handle 47 or may secure the services of a second person to assist in the operation to the extent of actuating the pumps. On the other hand the pump barrels seen more or less diagrammatically in Figure 8 at 10 and 11 may have their pump rods 17. and 18 actuated by the cranks 48 of a shaft 49 suitably inountediii bearings and provided with a pulley 50 which may be belt connected to any suitable source of power preferably a readily controlled source for instance an electric'motor the starting and stopping of which" canbe easily accomplished by the patient 7 On the other hand it is quite obvious that in either the hand or power actuated pumping arrangements described, there may be either two pump barrels, each of a single acting type, which I refer or a single pump barrel 51 asindicatec in Figure 7, of a dou- .ble acting type whose rod 52 actuates a plunger 53 movable between the ends of the barrel to which are connected inlet and outlet pipes 54 and 55 of the exhaust line and the 57 of the air apparently lifeless, the pressure supply tube 20 being in this case connected to one of the childs nostrils while the other nostril and month are held closed. 7 The. operator then blows gently through the mouth piece 38'and I tube 37, the air passing'through valve 34 of Figure 6 into the channel 33 and from there directly into the channel "31 for passage through the pipe 29,"air filter 25 and pipe 23 to the pressure line 20. This is repeated at intervals until natural respiration is induced. V V V 7 Iclaim: V V r 1. An apparatus for the purposes described including a casing, air pumping means in the casing including pumpbarrels and exteriorly projecting pump rods, the said pump barrels each having an intake andan ex-- haust, air lines connected to the intake of one barrel and the exhaust of the other barrel and including flexible tubes externally ofthe casing, air filtering means located in the casing within the air line leading from the exhaust of one of the pump barrels, other air lines, including external flexible tubes, leading from the intake of one of the pump barrels and the exhaust of the other barrel and separate from one another for independent application to the nostrils, and air filtering means located within the easing and in the air line of the last mentioned pair leading from the exhaust of one of the pump barrels, said exhaust ofsaid last mentioned pump barrel having a branch channel, a valve in the said branch channel, and an air line leading from the said branch channel and including a flexible tube projecting exteriorly of the casing.
